Aspects of the present disclosure provide methods, apparatuses, and systems for non-linear breathing entrainment. According to an aspect, a final breathing period is selected, and a current breathing period of a user is measured. A guiding stimulus configured to alter the current breathing period towards the final breathing period over an interval of time at a non-linear prescribed rate is output. A difference between the current breathing period and a target breathing period along the non-linear linear prescribed rate is determined. Based at least in part on the difference, the guiding stimulus and/or the non-linear prescribed rate are adjusted. The guiding stimulus and the non-linear prescribed rate may be stabilized, increased, or decreased to enable the user to reach the final breathing period.

Logic for modulating entrainment sequence with biofeedback

Aspects of the present disclosure provide methods, apparatuses, and systems for closed-loop sleep protection and/or sleep regulation. According to an aspect, sleep disturbing noises are predicted and a biosignal parameter is measured to dynamically mask predicted disturbing environmental noises in the sleeping environment with active attenuation. Environmental noises in a sleeping environment of a subject are detected, input, or predicted based on historical data of the sleeping environment collected over a period of time. The biosignal parameter is used to determine sleep physiology of a subject. Based on the environmental noises in the sleeping environment and the determined sleep physiology, the noises are predicted to be disturbing or non-disturbing noises. For predicted disturbing noises, one or more actions are taken to regulate sleep and avoid sleep disruption by using sound masking prior to or concurrently with the occurrence of the predicted disturbing noises.

Dynamic sound masking based on monitoring biosignals and environmental noises

Aspects of the present disclosure provide methods, apparatuses, and systems for non-linear breathing entrainment. As described herein, 'breathing entrainment' refers to guiding a user's breath or breathing. According to an aspect, an initial breathing period and a final breathing period are selected. Based on the initial and final breathing periods, a non-linear breath rate per minute sequence is determined. A guiding stimulus is output and aligned with the non-linear breath rate per minute sequence. The guiding stimulus is non-linearly altered with the non-linear breath rate per minute sequence to align with the final breathing period over an interval of time. The non-linear alterations of the guiding stimulus vary based on an amount of time the guiding stimulus has been output.

Non-linear breath entrainment

Aspects of the present disclosure provide methods, apparatuses, and systems for a personalized wake-up system. A sleep assistance device outputs a sound. In response to detecting a sound that exhibits one or more predetermined sound properties, actions are taken to adjusting the sound in an effort to wake the subject. Examples of predetermined sound properties include any sound detected over a threshold decibel level, sounds detected at a certain frequency spectrum. According to aspects, subject may further configure the system to alert the subject based on a set of personalized sounds the subjects considers to be important. According to aspects, the audio device or system is configured to determine the subject is awake based on collected biosignal parameters. The audio device or system takes further actions to disrupt the subject's sleep until the subject is determined to be awake.

Smart-safe masking and alerting system

A method of providing vagus nerve stimulation to a user is provided. The method includes the step of prompting, via a first audio cue emitted by an earpiece worn by a user, the user to inhale at a first point in time. The method may further include the step of prompting, via a second audio cue emitted by the earpiece, the user to exhale at a second point in time. The method may further include the step of stimulating a vagus nerve of the user with a first electrical signal generated by the earpiece at the second point in time. The first electrical signal may be applied to a concha of an ear of the user. The first electrical signal may be applied to an ear canal of the user. The first electrical signal may be applied to a tragus of the user.

Systems and methods for providing and coordinating vagus nerve stimulation with audio therapy

Systems and methods are provided that provide respiration entrainment cues to a user to encourage relaxation or a sleep state. The entrainment cues may be audible, visible, or tactile (or any combination). The entrainment cues include a rhythmic component associated with a target respiration rate and may include sub-components associated with a target breath architecture, such as an inhale-exhale cycle. The systems and methods detect the user's respiration to determine whether the user's respiration matches the entrainment cues or whether the user has fallen asleep.

Entraining respiration

Aspects of the present disclosure provide methods, apparatuses, and systems for dynamic starting rates for guided breathing. According to an aspect, a user's initial breathing metric is determined. A multiplier is then determined, where the multiplier varies as a function of the initial breathing metric within a range. The level of intensity of the multiplier may vary, and may be a dynamic feature based on the determination of the user's initial breathing metric. Once the multiplier is determined, the multiplier is applied to the user's initial breathing metric to determine a starting breathing metric for guided breathing. The starting breathing metric is slower than or equal to the user's initial breathing metric.

Dynamic starting rate for guided breathing

Aspects of the present disclosure provide methods, apparatuses, and systems for dynamically masking audible breathing noises determined to be generated by one or more sleeping partners. According to aspects, a subject's sleep is protected by detecting audible breathing noises in a sleeping environment, determining the audible breathing noises are not generated by the subject, and mitigating the perception of the audible breathing noises that are determined to originate from another subject, such as a bed partner, pet, etc. The dynamic masking reduces the subject's exposure to unnecessary sounds and reduces the chances of masking sounds disturbing the subject's sleep.
